To all whom it may concern:

Be it known that I, JOHN T. PSARBKI, a subject of the Czar of Russia, residing at Cleveland, in the county of Guyahoga and State of Ohio, have invented certain new and useful Improvements in Centrifugal Driers, of which the following is a specification.

In utilizing dyeing machines generally and in some particu ar instances, the vat or cylindrical kettle is provided with a distributing member com rising a false bot tom and a central distrlbuter pro'ecting upward from the center of the fa se bottom and both of these parts are provided with discharge openings. The distributing member in the tank forms the mass of material to be dyed in an annulus and if the cover placed on the dyeing machine is provided with perforations near the periphery only, then the circulation of the dye liquor is such that the mass of wool, cotton, or other material dyed is forced outward and up- Ward toward the upper outer corner around the machine, and the material nearest this point tightly compacted and more so than the material toward the bottom and center, so that the greatest density is at this point and rendering greater resistance to the circulation of'air through the mass at such point. The present machine, therefore, is

esi ied for use in conjunction with dyeing mac Ines generally but in more particularly for use in conjunction with the type of machine just set forth.

This invention, therefore, relates to im provements in devices termed whizzers which are otherwise known as centrifugal driers.

More specifically the invention contemplates the employment of a suitable-base having mounted thereon, in suitable swing ing supports, a casing in which is en ported a suitable motor having a vertica ly disposed shaft on the u per end of which is a basket having a soli bottom with acylindrical side wall provided with main charge perforations near its upper edge and smaller perforations througilzout the remain der of t e side. This has is is adapted to receive a false bottom, a central distributing member of a dyeing machine such as is set forth in my prior Patent No. 955,993 and in my prior application Ser. No. 546,414, filed February 28, 1910, and consists ofa false bottom and a substantially discy i al tral distributing member provided with a shank having an eye receivin a load hook for a suitab e hoist. Upon the basket is a cover having discharge openings near its peripher and an upwardly extending connection or receivin a hot air ipe leading from a suitable air eater not shown. This pipe passes into a suitable stufiing box in the connection. A further cover is provided upon the device and it consists of two halves bolted together'and secured to the periphery of the machine by suitable bolts. A suction pipe leads from a pump to the casing and serves as a means for exhausting the air. therefrom. It isalso part of the invention to provide the basket with blades around its periphery and upon its cover for causing the air to be thrown from the center of the device out through the perforated sides and into the casing from which. it is discharged through the exhaust pipe.

More specifically the invention relates to certain details of construction hereinafter set forth in the following description, drawings and claims.

Referring to the drawings, Figure 1 is a sectional view of a machine constructed according to my invention; Fig. 2 is a top plan view showing the two parts of the cover; Fig. 3 is a vertical section of a machine having fan blades around the peri hery of the basket and upon the cover; ig. 4 1s a top plan view in section; and Fig. 5 is a detail view ofa ortion of the side wall of the basket show- 1110 the large and small perforations.

11 carrying out the invention an {erred form'and construction of par may be employed so long as they possess the necessary. characteristics, but ave shown one embodiment in the drawin s which is highly efiective in operation, an in such exhbodr ment, 1 is a suitable base secured to the masonry or other foundation, and it is pro vided withn wardly projecting supports 2 each provid with a ball socket 3. Preferably there are three of these supports spaced equal distances apart around the machine, but only one is shown in the drawings. The socket 3 receives a ball 4 on the end of a bolt 5 passing through an opening in a flange 6 of the main w casing-is provided with a central opening 9 and with a flange 10 about such opening and receiving upon it a suitable motor casing 11. This motor may be-of any suitable type, and

of the cover with part preizzer casing 7. This since its constructionand arrangement coninto the main casing 7. 'Upon t is shaft,

which is tapered as shown, ismounted -a- I basket 13 having a sidewall 14 with small openings 14' therein through which Water and some .air passes, is through maln'discharge opemngs 15 ad acent to theupper edge of the side wall.

I The arrangementof the bottom of the basket is such that. the false bottom 16 and central distributing member 17 of a dyeing machine, .not shown, x with the mass 18 of material" thereon. The side wall of the basket receives a suitable cover 19 having a flange 20 extending down on the outside and provided with perforations 20' adapted 'to register with "the main discharge fopen'mgs 15.

discharge perforations 19. and *at the center with an upwardl extending domesshaped portion '21 provi ed with a connection 22 and receiving a pipe 23. A suitable stufiing box 24 is arranged about this pipe to prea suitable air vent leakage of air. The pipe 23 leads to heater of any design or construction, and not shown in the drawin s. The main casing'7 is provided with sultable cars 25- which receive bolts 26 upon fwhich nuts 27 are provided for holding the cover members 28 and .29 in place. These cover members are secured-together by bolts -30 passing. through ears 31. These two half cover members fit tightly about the pipe and abount the 'stufiing box and connection between the dome-shaped 5 member '21 and the air pipe. The suction e 32' leads into 1 the bottom of thecasing and it is connected chine is in the form of with any suitable 32". f

The material operated upon'bythe ma-' anannulus tightly .compacted toward the upper outer corner as a result of the dyeing operation in the dyeing machine, and on this account it is necessary to increase the dischargeat this as possible at the upper outer corner where the material is densest. Upon therotation of the basket and upon su "plying hot air "to the interior thereof an upon further causing the air to be drawn fromthe outer point, so as to permit as free a passage of air.

...casing, the material iszth rown against the side. and against the top, and the rushof air through the discharge openings causes thematerlal toseek the upper outer corner when the draft willthrough the mass of material when all mois- .ture willbe dried from'the mass and it will be ready for forations below the main discharge 'ope'n other work. The smaller Per:-

and a cover having be almost entirely,

aovaeee but the material at this oint is notv very dense and needs very little vent to ermlt a proper circulation of the air throng it.

In" the modification shown in Figs. 3 and. 4, .the basket 13 is provided upon its periph ery with blades 33 which are turnedslightly to the rear, as shown in Fi adapted to assistthe circu side wall. The cover may also be rovided which assist t e circuin the cover. I
